Trim excess fat from the steaks. Rub both sides of each steak with garlic, first rubbing the cut side of a garlic clove against the bone to roughly grate it, then spreading it over the meat.

Pour the crema di balsamico over both sides of the steaks, making sure it is spread evenly. Drizzle the olive oil over the top, turning to coat both sides. Set the steaks aside at room temperature while the grill heats up.

Season the steaks generously on both sides with coarse sea salt and black pepper to taste. Grill the steaks, turning them once, about 10 minutes for medium, or until done to your preference. Serve the steaks immediately with a lemon half on each plate.
